Definitions
- the invention relates to an artificial joint, in particular an artificial hand, consisting of a plurality of articulated members, at least one traction means movable by means of an actuator being provided for bending and for stretching the member.
- Such an artificial joint is known for example from DE-AS 22 45 503.
- tension bands which are fixed at the ends of the link tips, is already described therein, an actuating device for bending and a further actuating device for stretching and thus for resetting the link against the bending movement being provided in each case.
- this hand has an angled drawstring through which the thumb can be brought to a base support in different angular positions.
- a special arrangement is intended to ensure that the thumb can be moved in three swivel positions, so that the tip of the thumb can optionally be brought into contact with each individual finger or fingertip and thus very different gripping positions can be achieved.
- US 50 80 682 already shows an artificial hand that can be used as a prosthesis.
- the traction devices intended for bending and stretching the links are fixed at the tips of the outer links and are tightened by guides.
- EP 01 58 659 also discloses the use of elastic materials in an artificial hand, with additional guides for the traction means being connected to spring elements.
- the object of the present invention is therefore to design an artificial joint of the type mentioned at the outset in such a way that both a high load capacity for transmitting large forces and a large number of degrees of freedom for different gripping functions can be achieved.
- an artificial joint in which the individual links are connected to one another by an elastic connecting element in such a way that a joint gap between the links can be reduced by introducing a tensile force into at least one of the pulling means of the link.
- a large number of degrees of freedom can be achieved with a low tensile force, for example for largely forceless flexing of the link, by means of the connecting element, which not only serves to implement a multi-joint, but also, due to its elastic properties, a torsion about the longitudinal axis of the joint Limbs and a visco-elastic stretching of the joint (extension) in the direction, for example the fingertip, permitted.
- the joint gap and thereby the number of degrees of freedom are simultaneously reduced, as a result of which the joint is stiffened. This allows large loads to be held with restricted mobility.
- the properties of the artificial joint that can be achieved in this way which is primarily intended for prostheses, but is also fundamentally suitable for technical applications, therefore combine to a previously unknown extent both a high degree of mobility through a large number of degrees of freedom and a high load capacity depending on the tensile forces introduced.
- An embodiment of the present invention has been found to be particularly promising, in which the joint gap can be fixed independently of a bent or extended position of the link.
- the movement into the bent or the extended position is generally initiated by the fact that the tensile forces assigned to the movement differ from one another.
- a desired position of the link can therefore be set by both large and low tensile forces, provided that they are in equilibrium. By adjusting this level of equilibrium, therefore, the position of the limb is not changed, but rather the joint gap and thus the rigidity and the number of degrees of freedom, regardless of the joint position and the relative position of the limbs to one another.
- the number of degrees of freedom is determined by the gap width of the joint gap.
- the joint also has a reduced number of degrees of freedom as the gap width of the joint gap decreases.
- a reduced gap width which is achieved by introducing an increased tensile force, simultaneously leads to a gradual reduction in the number of degrees of freedom and to an increase in the rigidity.
- a modification of the invention in which the joint gap is reduced to zero when a predetermined tensile force is reached also proves to be particularly promising, with adjacent joint surfaces of the members lying flat against one another.
- the joint gap is therefore eliminated from a predetermined tensile force, so that the adjacent convex and concave joint surfaces lie against one another and the force is thereby transmitted directly from one link to the adjacent link without the joint being loaded in the process.
- the articulated surfaces can also lie against one another in a form-fitting manner, so as to specify a defined, stable articulated position when the maximum tensile force is introduced.
- the connecting element consists of a viscoelastic material, in particular of silicone.
- the rheological properties also yield a resilience and toughness, which, in particular, instantaneous force introductions are damped and therefore cannot lead to damage to the joint. At the same time, the tensile mechanical behavior of the joint is improved when stressed.
- the traction means are made of nylon. As a result, high tensile forces can be transmitted with a low susceptibility to wear.
- nylon has optimal sliding properties, so that the actuating forces to be applied by the actuator are comparatively low.
- Other suitable traction devices can also be implemented using steel wire and natural tendon material.
- the traction means could be wound up for shortening by means of a spindle or could have a hydraulic or pneumatic drive.
- an embodiment of the present invention in which the actuator is designed as a linear drive is particularly promising.
- the space requirement is comparatively small and at the same time the positioning is improved by an exactly reproducible adjusting movement.
- the actuator can also be accommodated inside the prosthesis having the artificial joint, whereby the wearing comfort can be significantly improved.
- the joint has a base support which carries the links and which has a plurality of base elements which are unaffected by the movement of the links and can be placed against one another by the traction means.
- the reinforcing effect of the joint can be used not only with the individual links of the joint, but also with the basic elements of the base support, which has a high degree of flexibility in the unloaded state and a high degree of dimensional stability when the tensile force is introduced.
- Another particularly expedient embodiment of the present invention is also created in that the limbs can be individually manufactured in accordance with the dimensions of the existing limbs of the patient. As a result, the properties and the visual appearance of the joint can be adapted to the patient's remaining joint. The functionality for the patient can thereby be significantly improved.
- the links can be produced using the rapid prototyping method, in particular using a laser sintering method.
- the links can be produced in a relatively short time.
- the required properties of the limb can be individually manufactured according to the patient's wishes.
- biocompatible materials can be used.
- the joint has components of living tissue.
- These joint components for example grown outside of the body and brought into the desired shape by means of a carrier material, enable a high degree of compatibility with the existing limbs and also have properties that cannot be achieved with materials that are foreign to the body.
- the muscle power of the body's own muscle fibers can be used by means of the actuator.
- the size of the actuator can be considerably reduced by essentially serving to transmit a pulse, while the actual application of force is achieved by the remaining or the body's own muscle fibers.
- the invention permits various embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below. This shows in an extended position in
- FIG. 1 shows a side view of two links of a joint according to the invention
- FIG. 1 shows an artificial joint 1 according to the invention, in particular an artificial hand, foot, knee, hip or shoulder joint, in an essentially force-free, stretched position.
- Two sections 2, 3 of the joint 1, which are only shown in sections and can be seen, are connected to one another by a viscoelastic connecting element 4. Due to the low introduction of force in the position shown, there is a joint gap 7 between adjacent joint surfaces 5, 6 of the links 2, 3, the gap width b of which reaches its maximum.
- the links 2, 3 can therefore not only be pivoted relative to one another about an axis perpendicular to the plane of the representation, but also twisted about a longitudinal axis or pivoted about further axes, the mobility being determined by the elastic properties of the connecting element 4 is.
- a stretched position of the links 2, 3 suitable for the transmission of large forces is shown in a reduced representation of the joint 1 in FIG. 2.
- the tensile forces introduced by means of traction means 8, 9, which are only indicated, omit in this position the joint gap 7 shown in FIG. 1, so that the adjacent articular surfaces 5, 6 of the links 2, 3 lie flat against one another.
- even large holding forces can be transmitted without problems, with the degrees of freedom of the joint 1 being reduced at the same time.
